I. INTRODUCTION Nile Tilapia (Oreochromis niloticus) is one of the most commonly cultured freshwater fish species in Nigeria. It is a prolific breeder, widely farmed across the nations of the earth and the third largest cultured finfish [1]. Oreochromis niloticus is a native of Africa [2], considered as a standout farmed fish because of its high nutritional qualities, fast growth rate, resistance to diseases and its ability to withstand sudden environmental changes [3]. In spite...

1. Introduction Mycotoxins are toxic secondary metabolites of fungi and are frequently found in a variety of agricultural crops such as cereals, fruits, and nuts. Mycotoxin contamination of crops and their carry over into the human food chain are of great concern as they are potent toxins and their toxicities may contribute to adverse health effects in humans [1]. In response to fungal infection and mycotoxin production, several cereal plants have been found to transform...

1. Introduction Wheat is susceptible to Fusarium head blight (FHB) world-wide which causes both yield and quality losses, in addition to contamination of harvested grain with mycotoxins, particularly zearalenone (ZEN) and type B trichothecenes such as deoxynivalenol (DON). There are strict regulations in place for maximum contamination levels of these two toxins to reduce accumulation in the human and animal food chains. Both mycotoxins can be produced pre- and post-harvest....

1. Introduction Fungal diseases are one of the main causes of large economic losses and deterioration in the quality and nutrient composition of fruits during the postharvest stage. They contribute significantly to the reduction of the shelf life of products during storage, contaminate fruits with mycotoxins, and reduce their market value. In the fresh production supply chain, such drawbacks have traditionally been overcome through the use of synthetic chemicals. However, due to...

1. Introduction Pathogenic microorganisms present in the environment are a menace for crops. At a worldwide level, diseases caused by plant pathogenic fungi significantly contribute to overall losses in terms of crop yield. To face this challenge, the use of traditional pesticides entails disadvantages related to handling hazards, cost, residues, and threats to human health and the environment. Consequently, European Directive 2009/128/EC established a framework to achieve their...

1. Introduction Rapeseed (Brassica napus L.) is one of the most important species among protein-oil crops grown in regions of moderate climates. The development of improved rapeseed varieties, i.e., free from harmful erucic acid and with a reduced glucosinolate content (the so-called double zero varieties “00”), has increased interest in this crop over the past decades. As a result, a significant increment in rapeseed cultivation has been observed and consequently,...

I. INTRODUCTION In Tanzania, a majority of the SM farmers use mash diets for feeding broiler chickens, and this has resulted in lower performance. The feed industry in Tanzania is less developed due to lack of analytical facilities, low quality of ingredients and lack of government policy enforcement on feed quality (Geerts 2014). Improving feed quality through physical processing and microbial enzyme supplementation can enhance broiler performance. Feeding pellets improves...

INTRODUCTION The nonstarch polysaccharide (NSP) portion of corn and soybean meal (SBM) – the 2 primary ingredients in North American poultry feeds – is complex and varies considerably across both ingredients. Exogenous NSP enzymes are supplemented to improve the digestibility of this fiber fraction for which no enzymes are secreted endogenously (Bedford, 1995; Cowieson, 2010; Kiarie et al., 2013). In this regard, diets composed mainly of...

INTRODUCTION The suggested BW of broilers (ROSS 308) will increase 50- to 55-fold at the age of 35 d as compared with the day-old chick weight (Aviagen, 2019a). Correct supplementation of dietary amino acids is crucial to support the exponential growth of broilers. Methionine (Met) is the first limiting amino acid in broilers; thus, meeting the requirements of Met plus cystine is crucial. The...

The North America specialty animal feed additives market is projected to accrue sizable revenue growth on account of rapid expansion activities in the eggs and meat industry. Animal feed additives are preparations or substances that are added for enhancing feed quality and boosting animal nutrition.
Major regulatory organizations like the U.S. FDA are classifying animal feed additives under the Generally Recognized as Safe (GRAS) category. This makes them safe for human and animal...

The growth graph of the global animal feed enzymes market is expected to display an upward trend in the coming years, due to the increasing preference of the people for nutritious diet along with a considerable rise in the disposable incomes, especially among the developing nations. In a report by the Government of Australia, the global consumption of meat increased to reach 360 million tons in the country by 2018.
With an evident increase in the consumption of animal by-products,...

DESCRIPTION OF PROBLEM Creatine is a necessary component in energy metabolism, supplying phosphate groups to adenosine diphosphate and recycling them to adenosine triphosphate (ATP) that can be used for maintenance and growth. This creatine-ATP recycling system does not occur in all cells, only in those where there is great variability in energy demand, including muscle cells [1]. Creatine is especially important in growing animals such as broiler chickens, as it is not only...

In the past, nutritionists did not pay attention to fibre in poultry feed formulations. Step by step the researcher as well as the industry in this decade has realised the importance of fibre in a poultry feeding strategy. The use of fibre in poultry has been, and still is, a major research topic at universities around the globe. Professor Mateos group from Spain as well as Prof. Svihus from Norway did a lot of research to explore the effect of different fibre sources on poultry health...

1. Introduction Soybean (Glycine max L.) is an economically valuable crop due to its high protein and oil content and wide variety of uses in food, agricultural pharmaceutical and industrial applications [1]. The United States produces 32.5% of the world’s soybeans (120 million tons/year valued at $31.2 billion), making it the second most valuable US crop [2]. In the southern US, high temperatures and dry conditions, along with poor management, can lead to...

INTRODUCTION Pioneer colonization of intestinal microbiota has a major effect on driving the maturation and composition course of microbial communities over time (Juricova et al., 2013; Rodrigues et al., 2019; Wilson et al., 2019). Later, the cross-talk between microbiota composition and immune cells has been highly associated with the establishment of immune competence (Crhanova et al., 2011; Chung et al., 2012; Schokker et al., 2017; Duan, 2018). Germ-free mouse models have...
